ポンプ。[Claims for Utility Model Registration] 1. A center case, a rotor that rotates within the center case, a vane held in a groove provided in the rotor, and a side plate in contact with the open end surface of the center case, and the rotor rotates. In a rotary vane type pump that performs pumping action by changing the volume of the pump chamber surrounded by the center case, internal rotor, vanes, and side plate end surface, when the volume of the pump chamber is reduced, the fluid is A rotary vane pump characterized in that a discharge hole for discharging discharge is provided on both the inner circumferential surface of the center case and the end surface of the side plate. 2. In claim 1, the discharge hole of the side plate is configured such that the discharge hole of the side plate end opens and closes within the opening/closing angle range of the discharge hole of the inner peripheral surface of the center case due to passage of the vane. A rotary vane pump characterized by having a set position.
